Hey @JimmyS - it really depends on the features you need and the number of concurrent users you anticipate. If you already have an external DB cluster, though, you can comment out the retooldb-postgres service and set it up as described here.
For sure - if you're not using either of those features, you can comment out anything about temporal in addition to the workflows-backend, workflows-worker, agent-worker, and agent-eval-worker services.
